APPARATUS FOR HEATING OR COOLING GASEOUS MEDIA.

SPECIFICATION forming part of Letters Patent No. 619,512, dated February 14, 1899.

Application filed April 1 1898- Seria1 N0. 676 ,094- (No model.)

To all whom it may concern:

Be it known that I, ADAM SLUCKI, a subject of the Emperor of Russia, residing in Warsaw, Russia, have invented certain new and useful Improvements in Apparatus for Heating or Cooling Gaseous Media, of which the following is a specification.

This invention relates to heating and cooling apparatus the casings of which have tubes passing through them through which the heat giving or absorbing medium flows, while for the heat absorbing or giving medium circulating around the tubes devices are arranged-for example, metal conductingsheetswhich determine a fixed direction for this medium between the tubes for the purpose of increasing the exchange of heat. In spite of these devices the exchange of heat between these two media is relatively bad, the cause of which is that the medium circulating around the tubes surrounds them in strata which are too thick and irregular. By means of this invention this objection is overcome by providing the apparatus with an arrangement which causes the medium circulating around the tubes to surround the tubes in ribbon-like thin wave-shaped strata in a direction transverse to the axis of the said tubes; For this purpose the casing of the apparatus inclosing the tubes is divided, not only horizontally, but also vertically, be tween the tubes by partitions into as many chambers as there are tubes. Each chamber incloses a tube and is connected with the next one by a slit which extends almost the whole length of the diaphragm in such a way that the cylindrical or prismatic spaces formed around each tube are connected into one or more rows. In this manner the medium circulating around the outer part of the tubes is compelled to pass around all the tubes in succession in thin broad wave-like strata. Thus the exchange of heat is increased to such an extent that the present apparatus, as has been shown by experiment, possesses an efficiency six or seven times as great as the apparatus of the same size as formerly constructed.

In the accompanying drawings, Figure 1 is a section on line 1 1 of Fig. 2 of one section of my apparatus. Fig. 2 is a section on line 2 2 of Fig. 3. Fig. 3 is a section on line 3 3 of Fig. 2 of my apparatus comprised of a plurality of sections. Fig. 4 is a transverse vertical section of a modified apparatus, and Figs. 5 and 6 are similar views of two other modifications.

Referring now to Fig. 3, the apparatus consists of a plurality of box-like casings or sections a, each of which has an ajutage b and is traversed by tubes 0. Between each two rows of tubes lying one over another are provided horizontal partitions d, Fig. 2, which pass right across the casing a in its transverse direction, but in its longitudinal direction start alternately from each side wall and do not extend quite to the opposite wall. These side walls have here the wave shape shown in Fig. 2, and the innersides of the four inclosing walls of the casing not connected with the tubes 0 are likewise waved. The form of the partitions and that of the inclosing walls is so selected that a cylindrical space 6 is formed around each tube 0 and a slit f left between each neighboring two hollow spaces, which extends through the easing parallel to the tubes 0. Thus the heads or crests f of the waves which are opposite to one another, separated by the slits f, form partitions which are vertical to the tubes 0.

The medium to be heated or cooled enters through the ajutage Z) and the first slit f into the first space 6. There it divides into two thin broad ribbon-shaped currents, one of which flows around the one half and the other around the other half of the outer circumference of the first tube 0 transversely to its axis. The two ribbon-shaped streams then unite and pass together through the second slit f into the second space 0, and so on, to the topmost space on the right,whence the united streams flow into the corresponding space of the next casing, and thence through all the successive spaces to the ajutage of this casing, which is connected by pipes with the place where the said medium is to be applied.

When the apparatus is made up of a plurality of sections, as in Fig. 3, the sections are secured together by a suitable means, as one or more rods g, having nuts 71. I

In the modification shown in Fig. 4 the waved partitions d are so arranged in the casing a that the spaces c surrounding the tube IOO 0 form two worm-like channels which unite at the inlet and outlet ajutages.

According to the modifications shown in Figs. 5 and 6 the space 6 surrounding each tube 0 is of prismatic shape.

The apparatus described is especially for use for superheating steam and heating air by boiler hot gases passing through tubes 0 or by a special fire; but it can be applied also to the condensation of steam and for the cooling of air by passing cold water or other cooling medium through tubes 0 instead of hot gases.

Having fully described my invention, What I claim as new, and desire to secure by Letters Patent, is--- 1. I11 an apparatus for heating or cooling fluids the combination of tubes a forming a conducting-way for one medium, a casing a inclosing said tubes, and corrugated partitions separating the tubes, the crests f of the corrugations extending between tubes 0 nearly to the plane of the axis thereof, whereby thin spaces eare formed around tubes cand connecting slits f, said slits and spaces forming a way or conduit for a second medium.

2. In an apparatus for heating or cooling fluids the combination of tubes 0 forming a conducting-way for one medium, a casing a inclosing said tubes, and corrugated partitions separating the tubes, alternate partitions extending from opposite sides of the casing and nearly across the casing, the crests f of the corrugations extending between tubes 0, whereby thin spaces 8 are formed around tubes 0, and slits f, said spaces and slits forming ways or conduits for a second medium.

3. In an apparatus for heating or cooling fluid the combination of tubes a forming a conducting-way for one medium, a casing a inclosing said tubes, said casing having corrugated walls,and corrugated partitions separating the tubes 0, as set forth.

4. In an apparatus for heating or cooling fluids the combination of a plurality of sections, each section having tubes 0 forming a conducting-way for one medium, a casing 60 inclosing said tubes, and corrugated partitions separating the tubes 0, forming thin spaces e and slits f, comprising a way or conduit for a second medium.

5. In an apparatus for heating or cooling fluids the combination of a plurality of sections each section having tubes 0 forming a conducting-Way for one medium, a casing a inclosing said tubes, corrugated partitions separating the tubes, and means for securing said sections together end to end, as set forth.
